1 Claim.

This invention relates to a detachable connection for auxiliaryreservoirsv and is especially adapted to be used in connection with alubri-v cation with a lubricating system for an internal 5. combustionengine as disclosed in the application of Vernon W. Thompson and Burt N.Pierce, led December 8, 1930, Serial No. 500,928, the object being toprovide means for connecting the auxiliary reservoir to the oilingsystem Without breaking the connection, thereby allowing the auxiliaryreservoir to be connected and disconnected to the oiling system.

Another and further object of our invention is to provide a gauge inconnection with the connecting member, whereby the amount of oil withinthe auxiliary reservoir can be ascertained at any time.

A still further object of the invention is to provide a connection inthe form of a sectional cap, one section being movable in respect to theother so that the threaded section can be screwed down onto the threadedneck of the receptacle, allowing the other section to remain stationary.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claim.

In the drawing,

Figure 1 is a perspective View of a portion of a can showing theapplication of our improved construction of connection thereto;

Figure 2 is a vertical section through a portion of a can showing ourimproved connection; and

Figure 3 is an enlarged vertical section through the `connection.

Irf the construction of lubricating system described in the applicationof Thompson and Pierce, we employ an auxiliary reservoir in the 40 formoi a can for supplyingY a lubricant to an oiler, which in turn suppliesoil to the induction pipe of an internal combustion engine, said supplybeing controlled by the vacuum in the intake whereby lubricant is fed tothe valves and the combustion chamber of an internal `combustion engine.

In the form of connection as herein sho-wn when used in connection withan auxiliary reservoir in the form of a can 1 having a threaded neck 2,we provide means for connecting the pipe system after a can becomesempty without breaking the connections or injuring the connections inany way leading to the oiler.

In carryingout our invention, we employ a sectional cap formed of aninternally threaded sleeve 3 and a disc 4, the sleeve being provided atone end with an annular flange 5 having a beveled portion 6 cooperatingwith the beveled periphery 7 of the disc 4 so as to form a tight jointbetween the two Vsections when the sleeve is screwed down on the neck ofthe can.

As herein shown the neck 2 of the can is provided with an annular flange8 at its upper end which is engaged by the bottomface of the disc 4 soas to form a seat therefor so that when the sleeve 3 is screwed down,the disc will be forced tightly in position on the iiange of the neckand a tight connection will be formed between the sleeve and disc. Thisallows the sleeve to be rotated in order to insert or remove the samefrom the neck of the can Without disturbing the connection to theoileras will be hereinafter fully described.

The disc has formed integral therewith an elbow 12, said elbow having acoupling 13 for connecting the pipe line 14 to the oler of thelubricating system to which the auxiliary reservoir is attached wherebythe pipe line leading to the oiler will remain in its original positionwhen the sleeve 3 is rotated so as to detach the sectional cap from thereservoir.

The elbow portion of the disc 4 is internally threaded and in saidposition the threaded upper end 10' of a pipe is mounted, which extendsdown into the receptacle and terminates short of the bottom thereof soas to allow the lubricant to be withdrawn from the bottom of the can andto prevent air from being conveyed with the lubricant` to the oilingsystem to which the device is adapted to be attached.

The disc 4 is also provided with a threaded opening 15 in which a tube16 is mounted in which is slidably mounted a gauge `rod 17 calibrated toindicate the quantity of oil within the container or receptacle,l saidrod terminating in a curved portion 18 atits upper end forming a handleby means of which it can be raised or lowered or de tached from thereservoir in order to determine the amount of oil within the same. Therod carries a cap 19 which seats on the upper end of the tube 16 so asto support it in its proper position.

From the foregoing description it will be seen that we have provided Vanauxiliary reservoir with a sectional cap carrying a gauge and means forconnecting the same to a pipe line leading to an oiler so that the pipeline can be connected to and a new can inserted and attached to thelubricating:

system without any danger-'ofiniing pipe lines leading from theauxiliary reservoir ytothel oiling system. l

What we claim is:

A reservoir for lubricatingv for internal combustion engines comprisinga receptacle having an externally threaded neck terminating in a at endportion, aflat disc mounted on the flat portion of said neck having anoutwardly beveled edge and provided with a tubular projection having acoupling, an internally 'threaded cap mounted on said neel; having anannular flange provided'witlffan undercut beveled portion cooperatingwith the beveled edge of said disc to allow said members to be rotatedin respect to one another, said disc portion being 'adapted to beclmged'tli'ereon in adjusted position by said cap pion and a pipe lineconnected to the coupling @if eel@ @ist Perdon;
